Patent EP-0424149-A1 (EP)
Inventor: REIDEMEISTER ERIC P
IPC: G01P15/125
Filed: 1990-10-18
Abstract: A capacitive acceleration sensor using a common PWB as one of the plates of the capacitive transducer and the wiring connections thereto. An acceleration input moves a capacitor plate to produce a measurable change in capacitance. An electronic signal conditioner (14) accurately converts the capacitance output to a voltage signal to provide an acceleration sensor featuring accurate DC performance. The transducer and electronics are disposed on a PWB making up a complete sensor package. In a first embodiment, the capacitor comprises a fixed electrode (3) on the PWB (1) and a movable acceleration responsive electrode (9) secured to a support (7) by a conductive resilient member (8), the support (7) coupled to an electrically conductive region (2) on the PWB (1) spaced from the fixed electrode (3) by a guard ring (4) to minimize stray charge between the capacitor electrodes. In a second embodiment, the movable capacitor electrode (21) is supported at its center by a pair of electrically conductive members (22, 22'), one coupled to an electrically conductive region on a substrate (24) spaced from the movable electrode by a sealing spacer (25). The fixed capacitor electrode is disposed either on the same substrate or a separate substrate on the opposite side of the movable electrode spaced from the movable electrode by a sealing spacer and having the fixed capacitor electrode thereon. The movable capacitor electrode can be secured at its center or at an edge and can be produced by stamping and/or photoetching and provide a single element where plural elements were previously required.

Abstract: Un appareil et un procédé permettant de procéder à un essai de traction sur des fibres, utilisent un crochet (24) sur lequel une fibre (22) est tendue, ainsi qu'une pince (26) destinée à serrer les extrémités opposées de ladite fibre (22) ensemble. Dans un autre mode de réalisation, on utilise deux pinces (94, 96) au lieu d'un crochet (24) et d'une pince (26). Lors d'une opération d'essai, on déplace le crochet (24) et la pince (26) l'un par rapport à l'autre afin de tendre la fibre (22), et on utilise des instruments de contrôle (58, 114) afin de contrôler au moins une caractéristique de la fibre (22) lorsqu'on la tend. On contrôle les forces de tension exercées sur la fibre à l'aide d'un transducteur piézoélectrique (58), et on contrôle les caractéristiques de section transversale de ladite fibre à l'aide d'un système à source de lumière (112) et à détecteur (114) orientant un faisceau de lumière (116) vers la fibre (22), et mesurant la lumière diffusée par cette dernière (22). On obtient des données multiples relatives à la fibre par essai d'un certain nombre de fibres d'un échantillon, et par superposition de représentations graphiques de caractéristiques de traction des fibres individuelles afin d'obtenir une représentation composite constituant des données multiples relatives à la fibre.

Title: Direction-determination logic.
Inventor: GLEIM GUENTER
IPC: G11B7/085
Filed: 1990-09-20
Abstract: A direction-determination logic is used in compact-disc players to establish in which direction the scanner is travelling across the tracks of the disc after either an intentional jump or an unintentional one caused by a knock, for instance. In order to determine in which direction the scanning light beam is travelling across the disc tracks, the phase difference between a track error signal (TE) and the envelope of the HF signal (HF) which generates the scanning light beam is only evaluated if the speed with which the light beam travels across the tracks is below a given value. The logic of the invention for the determination of the direction of motion of the scanner can be used in compact-disc players, video-disc players, DRAW-disc players and magneto-optical instruments.
